libtheme
this is a theming library for the plan 9 graphics system.
theme files are in ndb format. there is a sample in lib/theme.
theme files are read from $home/lib/theme, or /lib/theme if there is no theme file in $home.
applications using the theme library should call themeget to find color values. for example:
ulong col = themeget("rio", "background", DBlack);
this will look up an ndb record in the theme file that looks like this:
theme=rio
background=red
if the key background doesn’t exist, it will fall back to DBlack.
installation
mk install
cp lib/theme $home/lib/theme
B $home/lib/theme
existing applications will need patches to use libtheme. you can find some patches in patches/.
you will need to read the patches to figure out the appropriate database keys for a given application.
